A: Yes. We have volume discounts of up to 25%. Email us at
robb@robbmcperformance.com for more info.

Q: How long will it take you to ship my order after I pay?

A: If your order is only for a few items, we usually ship within 48 hours. If you place an order from our website, and we cannot ship within a few days, we will email you with an expected ship date and give you the option of canceling your order. Or email us at robb@robbmcperformance.com before you pay and we will let you know when we can ship.

Q: Should I buy the 550HP pump or the 1100HP pump?

A: If your car is street driven and the engine produces no more than
550 horsepower, the 550HP pump will work fine. If the car is primarily used for
racing or if the engine produces more than 550 hp, the 1100HP pump is a
better choice. The 1100HP not only produces more volume but the pressure can be
adjusted higher so that a regulator can be used. A high pressure pump
used with a regulator will provide steadier pressure than a low pressure
pump.

Q: What if I buy a 550HP pump and later find that I need a 1100HP pump?

A: Any 550HP pump can be upgraded to 1100HP specifications for $100. Email us at robb@robbmcperformance.com for more info.

Q: Do I have to use a pressure regulator with the 1100HP pump?

A: Not necessarily. The output pressure is adjustable and if you reduce
the pressure to about 7 psi, a regulator is usually not needed to prevent the
carb from flooding. However, reducing the pump output pressure from 14
psi to 7 psi reduces the pump output volume by about 50%. So if the
engine produces over about 550 hp, or if the car is used for racing,
increasing the pump pressure and using a regulator is highly recommended.

Q: You don't list a pump/starter/sending unit for my car. Can you make one?

A: In many cases, yes, and often for only slightly more money than one of our standard units.
Email us at robb@robbmcperformance.com with your requirement for more information.

Q: My car has a small factory "vapor return line" that was connected to the factory pump in addition to the inlet and outlet lines. Can I use
this line with a RobbMc pump?

A: Yes. To use the vapor return line with a RobbMc pump, order part number 1010 along with the pump.

Note: Part Number 1010 is automatically included with Buick pump Part Number 1002.

Q: The 7 psi produced by the RobbMc pump is too high for my carb. How can I lower the pressure?

A: If your car is equipped with a factory "vapor return line", you can purchase part number 1010 with your pump.
This will reduce pump pressure by about 1 psi. If your car is not equipped with a return line (or you need even less pressure), you can add a non-return style pressure regulator between the pump and the carb.
